Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional thermostat apparatuses face issues with inefficient mixing of low-temperature and high-temperature coolants, leading to unstable coolant temperature detection, increased engine stress, reduced combustion efficiency, and higher fuel consumption due to poor temperature control and structural complexities.
Innovation Solution
A thermostat apparatus with a high-temperature coolant conduit that directly contacts the temperature sensitive movable part, ensuring stable temperature detection and control by dominating the area where the movable part is disposed, thus enhancing the temperature dominant ratio and reducing structural complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the bypass port and deflector are spaced apart from the temperature sensitive movable part, then the high-temperature coolant can flow through the bypass port, but the high-temperature coolant cannot reach the temperature sensitive movable part efficiently, resulting in poor temperature detection and unstable coolant temperature control
Solution Approach 1:
The patent introduces a deflector as an intermediary component that actively guides the high-temperature coolant flow from the bypass port toward the temperature sensitive movable part. The deflector redirects the coolant flow path, ensuring that the hot coolant reaches the temperature sensitive movable part efficiently for accurate temperature detection and control.
2Ease of operation
If the bypass valve blocks the flow of high-temperature coolant before the temperature sensitive movable part, then the high-temperature coolant flow can be controlled, but the mixing of low-temperature and high-temperature coolants becomes inefficient, making it difficult for the temperature sensitive movable part to detect the coolant temperature
Solution Approach 1:
The patent applies local quality by creating a specific region near the temperature sensitive movable part where high-temperature coolant is concentrated through the deflector's guidance. This localized concentration of hot coolant ensures that the temperature sensitive movable part is exposed to sufficient high-temperature coolant for accurate detection, while the bypass valve maintains overall flow control.
3Temperature
If the low-temperature coolant and high-temperature coolant cannot be mixed efficiently at the temperature sensitive movable part, then the coolant flow can be controlled separately, but the temperature sensitive movable part cannot detect the coolant temperature accurately, resulting in unstable liquid temperature control and great temperature control range
Solution Approach 1:
The patent solves the mixing problem by introducing a spatial dimension solution through the deflector. Instead of relying on random mixing in the housing body interior, the deflector creates a directed flow path that brings high-temperature coolant into close proximity with the temperature sensitive movable part, achieving effective thermal interaction through spatial arrangement rather than volumetric mixing.

AI summary
An apparatus includes a movable temperature sensing member capable of sensing mainly the temperature of high-temperature coolant flowing in from a high-temperature coolant port and driving toward the side of the high-temperature coolant port in dependence upon the sensed temperature; a main valve fitted integrally to the movable temperature sensing member and constructed so as to render a low-temperature coolant port and a mixing compartment openable in conformity to the driving of the movable temperature sensing member toward the side of the high-temperature coolant port, thereby controlling the inflow rate of low-temperature coolant from the low-temperature coolant port to the mixing compartment; and a high-temperature coolant inducing part communicating with the high-temperature coolant port and adapted to regulate the flow of high-temperature coolant from the high-temperature coolant port toward the surround of the movable temperature sensing member and effect outflow thereof to the mixing compartment.
